ell i got my new tsais pipe and got it mounted. I wanted to hear what it sounded like so i put a splash of gas in the tank and ran it... thats where the problems started...when i emptied the tank and went to empty the motor of feul, it revved WAYYY up and didnt shut off till i put my finger over the pipe end. i didnt let it rev up too long...but i was wondering if it was just because it was super lean from being emptied or what?

Yep, that is correct as your motor is running out of gas it gets just a tad leaner and it will rev up somewhat when its right at the point of shutting off! Nothing to worry about...its normal

It sounded like it reved almost to max RPM...least i thought it did...it was more than just a second tho...it was maybe 2-3 seconds of high RPM...

at least you burnt all the fuel out of the engine so now you dont have to worry about the methanol attracting any moisture

There's more chance of Adsorbsion now than with a full tank.

i meant inside the engine
